lol at the above poster... as for the tattoo, that would have to be a giant tattoo... there is too much detail for it to be anything other than on your back or something, because ink sort of spreads when it's stabbed into your skin so there is only so much details you can fit into a square cm or a square inch of skin... let's say, you can't get a retina tattoo...

alternatively, you can have it look fuzzy

edit: p.s., there's too many light colors (white of the back of the coat, light grey of the skin) which are very hard to do on white skin (white tattoo shades are rare, expensive, and look like shit), and even harder on darker skins...

Hypothetically, I don't think it looks good. Looks exactly what it is: a video game character.
IF you were going for it, I'd take eror11's advice, PLUS have a good artist re-draw it so it looks more like a "real" character and not something where you can see the polygons.
